First Annelated Azaphosphole-Ferrocenes: Synthetic Pathways and Structures

The first annelated bis- and mono-3H-1,3-azaphosphole ferrocene sandwich compounds have been synthesized
from aminoferrocenes, and their X-ray structures are compared to those
of their selenide-protected PSe analogues, showing net discrepancies
both in metallocene backbone conformation and in fused-ring planarity.

首例稠合双-3H-1,3-氮磷杂环戊二烯（3H-1,3-azaphosphole）与单-3H-1,3-氮磷杂环戊二烯基二茂铁夹心化合物已由氨基二茂铁（aminoferrocenes）合成制备。研究人员将该类化合物的X射线（X-ray）晶体结构与其硒化保护P=Se类似物的晶体结构进行了比对，结果表明二者在茂金属骨架构象与稠环平面性两方面均存在显著差异。
